Where Alethea is most common

Compared with all babies born in each state since 1910, Alethea has been most common in Georgia (2.7×), Alabama (2.6×), and California (2.4×), and least common in Ohio (0.66×).

1,432 births recorded by state, 1910–2025. 2× means twice as common as nationally. States with fewer than 30 such births are left blank, and SSA withholds any year with fewer than 5 in a state, so small states read low.
